【摘要】 伴随着计算机与信息技术的高速发展,虚拟现实技术在科研、生产、生活中的应用越来越深入与广泛。作为虚拟现实技术最重要的表现形式,视景仿真是一种可以让用户产生身临其境感觉的交互式三维虚拟环境,可通过视觉、听觉、触觉甚至嗅觉上的实时感知让用户与所模拟的三维虚拟环境直接进行自然的交流。基于上述特点,虚拟现实技术已经成功应用于海洋仿真、地面战争模拟、车辆驾驶仿真、飞行仿真、城市规划仿真、三维游戏开发、建筑设计漫游等方面,并不断地向新的领域扩展。现代战争科技水平越来越高,对武器精度的要求和军事人员的综合素质要求也越来越高,因此,世界各国不惜耗费巨资进行各种武器装备试验和军事人员实战训练,不断提高军队的战斗力。但是真实作战训练会出现许多实际问题比如：有一定危险性、费用过高以及受真实地理环境的限制等等,而虚拟现实技术可以很好的模拟高度逼真的三维虚拟战场环境、模拟和控制各种武器装备的运动和功能以及模拟实战中的各个环节,很大程度上解决上述实战训练中的问题,从而将虚拟现实技术应用到军事领域渐渐成为一种潮流和趋势,因此近些年虚拟现实技术在军事领域的应用越来越广泛和深入。在这样的背景下,为了方便新一代车载武器系统的研究,本课题志在研究开发一个车载武器系统起竖仿真平台,该平台能够实现在不同的仿真模式和导航参数设置下,模拟车载武器发射前的各种起竖过程,并同步进行导航解算仿真,最终实时而直观地描述车载武器系统在各种导航和起竖方式下的解算精度。论文首先基于Multigen-Paradigm公司的Creator建模软件和Vega三维视景仿真技术,深入研究了车载武器系统和地形三维建模,以及三维虚拟场景的创建、实时仿真和控制。然后设计编写一种适合于本课题的具有各种参数接口的捷联惯导导航算法,研究不同仿真模式下的导航解算仿真。接下来在VC++6.0开发环境中设计开发起竖仿真平台框架,以独立模块的形式加入三维视景仿真模块和惯组导航解算模块,并研究设计一套科学高效的运行流程和控制逻辑,确保平台能够正确、稳定和高效地运行。最后设计一个友好、美观、大方的起竖仿真平台界面,实现人机交互功能。经过大量的后期测试,平台成功地实现了预期的功能,运行良好。更多还原

【Abstract】 With the rapid development of computer and information technology, the application of Virtual Reality Technology becomes more and more deeply and widly in scientific research, manufacture and daily life. As the most important representative form, Scene Simulation is a interactive 3D visual environment which can make people feel like they are in reality, it can make the user and the 3D visual environment communicating directly by the feeling on vision, hearing, touch and smell. Hence, Virtual Reality Technology has been used in sea simulation, war simulation, driving simulation, flying simulation and so on, it will be used in more and more area.The level of modern warfare technology bocomes higher and higher, so the precision weapons requirements and the overall quality of military personnel requirements bocomes higher and higher, therefore, the military expenditure was spared for a variety of weapons and equipment testing and combat training of military personnel to continuously improve the armed forces combat effectiveness. But There will be many practical issues in real combat training such as:There is some risk, high cost and subject to geographical constraints, Virtual Reality Technology can be a very good three-dimensional simulation of highly realistic virtual battlefield environment, simulation and control of the kinds of weapons and equipment movement and function as well as all aspects of simulation of actual combat, combat training in large part to solve the above problem, which will be applied to virtual reality military gradually become a trend, so the application of Virtual Reality Technology in the military becomes more and more extensive and in-depth in recent years.Under the background just mentioned above, In order to make it easy on the research of a new generation of the Car Weapon System, this paper aim at designing an Erecting simulation platform of Car Weapon System. This platform can simulate all kinds of erecting process of the Car Weapon before launching and achieve the simulation of navigation calculation at the same time with different simulation models and navigation parameters, it can also describe the calculation precision of the Car-Weapon System with different navigation and erecting process timely and directly.Firstly, this paper has made a deep research not only on how to create the 3D models of the Car Weapon System and terrain but also on how to create, simulate and control the 3D virtual scene based on Creator software and Vega 3D scene simulation technology producted by Multigen-Paradigm Company. Then it designed and programmed an algorithm of Strap-down Inertial Navigation System with all kinds of parameter interface which is suitable for this paper in order to make a research on the simulation of navigation calculation under different simulation modes. The next work is to design the frame of the erecting simulation platform in the VC++6.0 development environment, then importing the 3D Scene Simulation Module and the Navigation Calculation Module into the frame. Then Designing a scientific, efficient running flow and control logic to make sure the platform can work accurately, steadily and efficiently. The last work is to design a friendly, beautiful and handsome interface in order to achieve the function of Human-Computer interaction.After testing and debugging, the platform has achieved prospective function and works well.更多还原
